The Notorious hasn't entered the Octagon since defeating Eddie Alvarez way back in 2016 but returns on Saturday night in Las Vegas when he takes on Khabib Nurmagomedov for the lightweight title.
Unsurprisingly, McGregor was the headliner as the UFC was staged in the Big Apple for the first time and he marked the occasion by joining all-time greats Randy Couture and BJ Penn in winning UFC titles across two weight classes, while he was the first to hold two belts at the same time.
McGregor went off on one on the show and threatened basically everyone, and in particular Khabib's crew, saying they need to watch themselves.
"I spent my entire life's work to win those two world titles", he continued. I set out a goal, I put everything, absolutely everything, sacrificed so much times, sacrificed so much to gain those world titles. "Had many things going on".

But officials have been meeting behind the scenes before a key summit in Brussels on October 17 and 18. But there is still no agreement on some issues, including how to avoid new checks on the Irish border.
"I'm certainly considering a few options", McGregor told ESPN.
"I'm hungry to compete and we're here right on the cusp of it". He is coming off a unanimous decision win against Al Iaquinta in April at UFC 223.
That Brooklyn event was overshadowed by McGregor gatecrashing a media day. He gave me a rematch, I give him a rematch. I feel his brain is going to rattle when he gets a clatter off me. I will be prepared for any scenario.
The best estimate for the start of McGregor vs Nurmagomedov main card is 3am (UK time), meaning we could be waiting until well after 5am if the matches on the undercard go the full distance.

If you thought this comeback fight was a one-off deal for Conor McGregor, think again.
"I've already been mapping out what I would want to do next", McGregor said.
In the co-feature, former interim lightweight champion Tony Ferguson (23-3 MMA, 13-1 UFC) takes on ex-champ Anthony Pettis (21-7 MMA, 8-6 UFC). About a month or two ago in preparation for this, when that fight got announced as co-main, I was like man if Khabib bottles this fight like he has bottled many fights before, if he bottles this one, no disrespect to those other two but I don't give a f- about those other two, to step in, I think I would have just disappeared back into the shadows and got that man somewhere else outside of here.
"Nate Diaz will always have a rematch of of me no matter what happens". I know the 170lb belt has also just been defended and I know Tyron [Woodley], the current welterweight champion, is itching for that one - like they all are. When it will happen, I don't know. Everyone is looking for it. Let's see what happens.
